Gasper is out of the lineup for Sunday's game against the Giants.
Though he'll head to the bench while southpaw Matt Wilkinson starts for the Giants, the switch-hitting Gasper looks to have moved into a regular role as the Red Sox's designated hitter versus right-handed pitching since being recalled from Triple-A Worcester a week ago. While starting in each of Boston's last five games, Gasper went 5-for-15 with three home runs, one double, two walks, eight RBI and three runs.
